SOHLEGEL, OF ROCHESTER, NEW YORK, ASSIGNOB TO SGHLEGEL MFG. COMPANY, OF ROCHESTER, NEW YORK, A. CORPORATION OF NEW YORK WINDOW CHANNEL Application filed October -14, 1927. Serial No. 226.249.

The present invention relates to window channels and more particularly to the type designed for slidably receiving one edge of a glass sash like those employed in motor vehicles. An object of this invention is to provide a construction in which the glass sash tends to force the sides of the channel into close fitting engagement with the opposite faces of the sash. Another object of the in- 39 vention is to provide a construction in which the two side walls of the channel are resiliently mounted so that they may move toward opposite faces of the sash, provision being made for forcing said side walls toward the in opposite faces of the sash upon the introduc tion of the sash'into the channel. Still another object of the invention is to provide a channel with resiliently mounted side walls movable at their free edges toward and from the opposite faces of the sash, the channel having within it means which is engaged by the sash upon its introduction into the channel to move the sidewalls at their free edges toward the opposite faces of the sash.

To these and other ends, the invention consists of certain parts and combinations of parts all of which will be hereinafter described: the novel features being pointed out in the appended claims.

In the drawings:

Fig. 1 is a perspective view of a window channel constructed'in accordance with this invention;

Fig. 2 is a transverse section through the channel showing ,the condition of the latter prior to the introduction of the sash; and

Fig. 3 is a similar section showing the sash introduced into the channel and the free edges of the side walls of the channel moved toward the opposite faces of the sash.

In carrying out this invention there is provided a channel body comprising a bottom wall 1 and two side walls 2. This body may be made of any suitable material, but the side walls 2 should be permitted tomove toward and from each other at their free ed es. This result, in this instance, is. accomplis ed by making the channel body of a resilient material which will permit the side walls 2 to swing toward each other at their free edges. In this instance, the channel body is formed from pulp material, such as leather board or paper board, either molded or pressed into channel form preferably with the side walls converging toward their free s edges in order to facilitate their swinging inwardly.

Means is provided which upon the introduction of the sash 3 into the channel will draw the side walls inwardly at their free on edges toward the faces of the sash. This means is arranged in the channel and comprises, in this instance, two webs 4 formed from a single piece of pliable sheet material secured by a stitching 5 to the bottom wall of the channel at the middle of the latter. The webs diverge, in this instance, from the stitching 5 at angles to the plane of the sash and extend to the free edges of the side walls 2 in spaced relation to such side walls. The sheet material, in this instance, is then extended downwardly at 6 on the outer faces of the side walls 2 and thence at 7 over the rear face of the channel body, the two edges of the sheet'material being overlapped and being held, in this instance, by the stitching 5. The sheet material of which the webs and channel covering is formed maybe any pliable sheet material such as a woven textile fabric or felt. When a woven textile fabric is employed a pile surface 8 may be provided -upon the opposed faces of the two webs 4-,

the pile being either cut oruncut but preferably being relatively long so that a large number of resilient closely assembled fingers are provided in order to resiliently support the sash 3 and at the same time to prevent a smooth condition developing on the surfaces engaging the sash.

It will be noted that a single line of stitching secures the pliable sheet material to the bottom of'the channelbody and also to the rear face of the channel body. This stitching is permitted, due to the fact, that the channel body is formed of a pulp material through which the needle of the sewing machine may readily pass. It is apparent however, that the invention is not limited to making the channel body of pulp material. 10c

What I claim as my invention and desire to secure by Letters Patent is: Y

1. The combination with a channel body having its two opposite side walls resiliently supported, of two webs of pliable material secured to the bottom wall of the channel body, extending into diverging spaced relation to and connected with the side walls of the channel body.

2. The combination with a channel body having its two opposite side walls resiliently supported, of a pliable piece of sheet material secured to the bottom wall of the channel body near the middle of such bottom wall, extending from said secured portion about the free edges of the side walls into spaced relation to said side walls, thence over the outer faces of the side walls to the rear face of the channel body.

3. The combination with a channel body having converging side walls resilientlycon: nected to the bottom wall of the channel body, of two webs of pliable material secured to the bottom wall of the channel body and extending in diverging spaced relation to and connectedwith the free edges of the side walls.

4. In a window channel, the combination with a channel body having a bottom wall and side walls, of a sheet of material lying Within the channel and extending over the outer faces of the side walls and the back of the channel, and stitching passing through that portion of the sheet lying within the channel, and also through the bottom of the channel and those portions of the sheet extending over the back of the channel.

5. The combination with a sash, of a channel body having its two opposite side walls resiliently supported, and means arranged in the channel of the body, and distorted by the sash'to hold the free edges of the side walls toward the opposite faces of the sash, said means comprising two non-metallic pliable webs each extending inwardly from the free edge of a side wall of the channel body and1 lying flat against opposite faces of the sas 6. The combination with a sash, of a channel body having itstwo opposite side walls resiliently supported, and a piece of nonmetallic pliable sheet material extending from the free edges of the side walls, of the channel body, distorted by the sash to hold sides of the sash and spaced from the side walls.

8. The combination with a sash, of a channel body having two opposite side walls resiliently supported, and non-metallic pliable sheet material supported in said channel and held under tension by pressure of the sash thereon, such sheet material having connection with the opposite side walls to place them under tension and hold them toward opposite faces of the sash, and such sheet material also engaging the edge of the sash and extending. about opposite corners at said edge and inwardly in parallel relation to and in engagement with the opposite faces of the sash from said corner.

site sides of the sash, and lying when distorted flat against opposite sides of the sash.

7. The combination with a sash, of a channel body having converging side walls resiliently connected to the bottom wall of the channel body, a piece of non-metallic pliable sheet material extending into the channel from the free edges. of the two side walls of the channel body lying fiat against opposite
